Abstract

The adoption of the Software Defined Networking (SDN) paradigm is experiencing rapid growth, extending beyond typical datacenter networks to encompass 5G and IoT deployments. This expansion is primarily driven by the inherent flexibility offered by SDN in terms of network management and control. Mobile Ad-Hoc Networks (MANETs) have not yet fully embraced the advantages of the SDN approach due to their specific requirements arising from the dynamic nature of mobility and the unpredictable conditions of the wireless medium. The progress of adoption has been impeded by technical obstacles and the inherent conflict between the centralized nature of SDN and the decentralized approach of conventional MANET protocols. This paper introduces our implementation of a comprehensive SDN scheme that aims to address the divide between different networking approaches by integrating the advantages of both worlds. Our prototype has the capability to integrate with 802.11 Ad-Hoc networks. It provides several important features: a) fault tolerance for the SDN controller, which involves recovering from failures by electing a new controller, b) dynamic network topology discovery, and c) the ability to deploy globally optimal routing policies, based on the Multicommodity Flow Problem (MCFP), and following a cross-layer approach that utilizes the 802.11 MAC layer statistics. The applicability and performance benefits of our framework were assessed through the evaluation of our proposed scheme in contrast to a traditional MANET routing protocol.

基于SDN架构的802.11 manet路由优化

软件定义网络（SDN）范式的采用正在快速增长，从典型的数据中心网络扩展到包括5G和物联网部署。这种扩展主要是由SDN在网络管理和控制方面提供的固有灵活性驱动的。由于移动性的动态性和无线介质的不可预测条件所产生的特定要求，移动自组网（manet）尚未完全接受SDN方法的优势。由于技术障碍和SDN的集中特性与传统MANET协议的分散方法之间的内在冲突，采用的进展受到阻碍。本文介绍了我们的全面SDN方案的实现，该方案旨在通过集成两种网络方法的优势来解决不同网络方法之间的鸿沟。我们的原型具有与802.11 Ad-Hoc网络集成的能力。它提供了几个重要的特性：a) SDN控制器的容错，包括通过选择新的控制器从故障中恢复，b)动态网络拓扑发现，以及c)基于多商品流问题（MCFP）部署全局最优路由策略的能力，并遵循利用802.11 MAC层统计的跨层方法。与传统的MANET路由协议相比，通过对我们提出的方案的评估来评估我们框架的适用性和性能优势。
